VATENT C. WAHL AND ALBERT H. STEN'ERSEN; OF CHICAGO, ILLTNOIS, ASSIGNORSTO THE i COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWAREFOUNTAIIN-PEN-FILLI'NIG DEVICE Application filed October 24, 1925.serial m. 64,485.

Our invention relates to a device which may be readily applied to an inkbottle or the like for facilitating the filling of a fountain pen, andamong the objects of our invention are the following:

To provide a device for aiding in the fillingi of fountainpens. v p

0 supply a device-whereby the ink in the bottom 0 a bottle may beconveniently used for the filling of a fountain pen. 1

To supply a device whereby a fountain pen may be more quickly andefiiciently filled.

To provide a.device whereby the pen point of a fountain pen may beprotected from injury by contact with the hard glass or other materialof a bottle.

' Another object of our invention is to provide a device containing acup .of suflicient depth which is normally filled with ink so that whenthe penis introduced the filling is accelerated.

A. further object is to provide a device easily attached to a bottle andavailable for immediate use in aiding the filling of a fountain pen,and. such further objects, advan-.

tages and capabilities as will later more fully appear.

Our invention further resides in the combination, construction andarrangement of parts shown in the accompanying drawings,.and'

while we have shown therein a preferred embodiment we wish it understoodthat the same i is susceptible of modification and change withoutdeparting from the spirit of our invention.

Referring to the drawings- .body member 10, having formed therein andextendin from the lower side thereof an axially 'sposed depending hollowcup 11 forming the well 13. The body member 10 is formed with a mouth 12continuous with thewalls of the well 13 for the reception of I afountain pen. I The exterior of the cup 11 is formed with a groove 14for the reception of a tube 15, which extends through an opening in boss16 into communication with passageway '17 leading into the upper portionof.

well 13. -When the tube 15 is placed in the groove 14 and inserted intotheopening in boss 16 a passageway for the flow of ink or the like iscreated, reaching from the-end of tube 15 to the interior of the well13.. An air passage 18 extends through the body member as plainly shownin Figspl and 2, to prevent the creation of a partial vacuum within thebottle above the ink level. The ,body mem-. ber 10 may be formed ofrubber or other suitable material.

In operation the body member 10 with the tube 15 attached as shown isinserted into the neck of the bottle (see Fig. 1). A fountain.

pen point 21 is then introduced into the mouth" of the body member, thelower circumferential edge of the pen section upon the application of alittle pressure forming an airtight connection with the walls of thebody member mouth 12. Before introductionlofthe" .pen point into themouth 12 the self-filling arm 22 of the fountain pen should be moved toopen position to expel any ink and air that may be in the'barrel of the.pen. After in-. troduction of the pen in mouth 12 the self-fill ing arm22 ofthe fountain pen is closed and a suction is thereby caused by thereturn of the compressed ink sackto normal position which causes the.ink to flow upwardly through the tube 15 into the interior of the well13, and through the ink feeding chan- Fig. 1 is a vertical sectionthrough an ink.

nels into the ink sack of the pen.

After a certain amount of suction the ink not used by the pen remains inthe well so that upon the next operation the filling is more immediatethan the first filling. In this dway a normal immediate filling-is.assure The air hole l8 acts to replenishiithe air in the inkhottleand'tli-us prevents a' vacuum v 'or partial vacuum within the bottle"jabove the ink. In this way constant and positive tSllCtjOD. uponoperation of the filling "arm 1 22 is insured.

It will readily be seen that the tube 15 extends to the remote depths ofthe ink bottle 20, and thus insures that the ink will be available foruse substantially to the bottom of the bottle. When filling a pen in theold way, without our device, it is necessary to have a substantialamount of ink in the bottle to bring the level of the ink sufficientlvhigh for filling purposes. Our device preferably, having a soft mouthalso pre 19 vents any danger of the pen'being injured by contact withroughor hard surfaces.

Having now described our invention, we claim Y 1. In a fountain penfilling device, the combination with an ink bottle of a body membprfitting and normally fixed within the mouth of said bottle and providedwith a vent, a depending well and'a mouth leading through the top of thebody to the well, sai mouth being so formed as to permit a tig tengagement of the shoulder-of a fountain pen therewith below said vent,and a depending feed tube having its upper end communicating with saidwell at a position" above the bottom thereof so as not to drain the wellwhen the device is not in use.
